v Specification of Letters Patent.

Application filed. July 21, 1910.

Patented Nov. *7, 1911. Serial No. 573,022.

To all whom it may concern:

Be it known that I, HENRY L. Con, a citizen of the United States,residing at l/Varren, in the county of Trumbull and State of Ohio, haveinvented a certain new and useful Improvement in Agitators, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings.

The object of this invention is to provide a very simple and eflicientdevice for agitating paint or other materials in barrels.

My agitator is adapted to be applied to an ordinary barrel and includesmeans within the barrel for stirring or agitating the contents, and asuitable crank mechanism above the barrel head for rotating the stirrer.The crank mechanism is adapted to lie snugly againstthe head of thebarrel and out of the way, when not in use, while it is ready for usewhenever desired. For this purpose it is provided with an inwardlyextending tubular crank-shaft which engages the shaft of the stirrer andhas external screw threads screwing into the barrel head. Accordingly,these threads may hold the crank member snugly against the head of thebarrel, closing the opening which the stirrer shaft occupies, whilerotations of the crank screw its tubular shaft out of the barrel head,and thereafter it may rotate freely, operating the stirrer as long asdesired.

The drawings clearly illustrate my invention.

Figure 1 is a plan of a barrel to which it is applied; Fig. 2 is avertical section of the upper portion of the barrel, showing the crankin its idle position; Fig. 3 is a similar view showing the crank in theposition it occupies in giving continuous rotations to the agitator; andFig. 4iis a perspective of the crank itself.

As shown in the drawing, A represents any suitable barrel and a the headtherefor. Within this barrel is an agitator having an upright shaft Band any suitable projections or wings carried thereby, as indicatedconventionally at b. The particular form of the stirrer is immaterial.In ordinary practice, owing to the tendency of the paint to settle atthe bottom of the barrel, the mechanism is designed particularly tooperate with most efficiency near the bottom portion of the barrel, butit is considered suflicient to show one stirrer blade, as illustratednear the top of the barrel, which is to be taken as an example of anyinternal construction. The agitator shaft B is made non-circular, atleast adjacent to its upper end, whereby it may be engaged and driven atsuch upper end. This shaft occupies an enlarged central hole in thebarrel head, the shaft terminating, preferably in about the plane of thetop of the head.

The crank, wherein the novel features of this invention reside, consistsof the body C and a handle D. The body, which may be a single casting,has a projecting hub or sleeve 0, which is provided with a square orother non-circular bore a. This hub is adapted to extend through thecenter opening in the barrel head a and surround and embrace the shaftB. On its exterior, the hub 0 has threads 0'' which screw into thebarrel head. By this means, the crank body, by being rotated, may beturned down tightly against the head. The crank body has a flaringdisk-like portion 0 around the hub, which comes down snugly against theupper face of the head when the crank is in its idle position, therebypreventing any leakage about the hub. The handle D is pivoted by a pin Ein a recess 0 in the crank body. This recess is of sufficient size toreceive the handle when it is turned down in the position shown in Fig.2, and the handle may be securely held in this position for shipping bya wire F. for example, surrounding the body and handle. This recess 0has preferably an open bottom at 0 preventing the accumulation of dirtin the recess. The bore 0 extends not only through. the hub 0, but upinto the body of the crank, so as to allow considerable leeway in theposition which the upper end of the shaft B may occupy, thus providingfor barrels differing somewhat in height. The portion of. the bore 0which extends into the body above the hub c is inclosed by a suitableportion of the body, which may conveniently be formed angular, like anut, as shown at 0 This not only gives a neat appearance, but furnishesmeans for at taching a wrench, should it ever be needed. The threads 0on the hub 0 are preferably left hand threads, the result being that aright hand rotation of the crank (which is the natural way for operatingthe agitator) first screws the hub out of the barrel head, asv shown inFig. 3; and then, the continued right hand rotation serves to operatethe agitator, as desired, the thread riding idly above the barrel head.When the agitating operation is completed, an ordinary left handrotation of the crank screws it back into home position, as shown inFig. 2.

Having thus described my invention, what I claim is 1. An agitator forbarrel contents comprising stirring means within the barrel, and a crankon the outer side of the barrel head having a hub extending through anopening in the barrel head and engaging the stirring means, said hubhaving an external thread screwing into the barrel head, wherebyrot-ation in the proper direction makes a snug engagement of the crankagainst the top of the head.

2. An agitator for barrel contents comprising stirring means within thebarrel, a driving member on the outer side of the barrel head having ahub extending through an opening in the barrel head and engaging thestirring means, said hub having a thread adapted to screw into thebarrel head and having a plain portion below the thread adapted tofreely occupy the opening in the head when the thread is screwed out ofit.

3. An agitator for barrel contents comprising mechanism within thebarrel having a shaft occupying an opening in the barrel head, acrankhaving a hub occupying such opening, the hub and shaft being slidablewith reference to each other but having a driving engagement, and athread on the exterior of the hub.

4:. An agitator for barrel contents comprising mechanism within thebarrel having a shaft occupying an opening in a barrel head, a crankhaving a hub occupying such opening and embracing the shaft, the hub andshaft being slidable with reference to each other but having a drivingengagement, threads on the exterior of the hub adapted to engage thebarrel head, the body of the crank being provided with a disk-likeextension adapted to fit snugly against the top of the head when thethreads have been sufficiently turned into' the opening in the head.

5. In a device of the character specified,

the combination, with a barrel and agitating mechanism, of a crankhaving an externally threaded hub adapted to have'a driving engagementwith the agitating mechanism,the threads of said hub being adapted tohave an engagement with the barrel head whereby rotation may bring thecrank snugly against the barrel head.

6. In a device of the character specified, the combination with a barreland agitating mechanism, of a crank having an externally threaded hub,adapted to have a driving engagement with the agitating mechanism and adisk-like extension projecting above the threads.

7. In a device of the character specified, the combination, wit-h abarrel and agitating mechanism, of a crank having an externally threadedhub adapted to have a driving engagement with the agitating mechanism,and an angular bore within the hub, the threads of said hubs beingadapted to have an engagement with the barrel head whereby rotation maybring the crank snugly against the barrel head.

8. In a device of the character specified, the combination, with abarrel and agitating mechanism, of a crank having an externally threadedhub adapted to have a driving engagement with the agitatingmechanis1n,the body of the crank having an elongated recess, the crankhandle being pivoted to fold within the recess, and a disk extension onthe crank surrounding the hub and adapted to be brought into snugengagement with the upper surface of the head by the rot-ation of thecrank.

9. In a device of the character specified, the combination with a barreland agitating mechanism, of a crank having an externally threaded hub,adapted to have a driving engagement with the agitating mechanism thebody of the crank having an elongated recess, and the crank handle beingplvo-ted to fold within the recess, the recess having an opening on itsunder side whereby it is selfcleaning.

In testimony whereof, I hereunto aflix my signature in the presence oftwo witnesses.
